Question

Quizplus · Accepted Answer

Antigens can be recognized by T cells or B cells, which is a fundamental aspect of the immune response. Antigens are not always derived from pathogens (they can come from non-pathogenic sources), not always proteins (they can be carbohydrates, lipids, or nucleic acids), do not have to be microbial in origin (they can be from any source, including self-antigens in autoimmune diseases), and they do not usually cause cellular damage themselves (it's the immune response to the antigens that can cause damage).
